After reading many posts, I still am unclear on his one. I have a 2012 Bonnie with 800 miles. At 500 I had Arrow 2-2's installed along with the corrwponding map from the dealer. I have noticed it seems rich at start up but evens out. There is no back firing on deceleration whatsoever. I put a K & N filter in and have been toying with the idea of removing the snorkel. My question is, is the 20 min. adaptive cycle necessary if I remove the snorkel? I ask because I did this very thing and am not sure if there was much difference sans snorkel. So I put it back on and did the cycle again. This time, my pipes really started to blue...actually, they purpled. I let the bike cool, restarted it, and rode for 60 miles on some back roads. Everything seemed fine.

Too late now, but although it helps to do the adaption procedure after downloading a new map by the 20-minute idling method, the dealer can carry this out in just a few seconds with his diagnostic tool.

If done at home it helps to temporarily disable the AI to minimise exhaust temperatures that cause the pipe discolouration.

A scan of the procedure from the manual here, see the second note in bold characters detailing the fast dealer routine:

Ok, thank you. Just one more question, can idling the bike for twenty minutes potentially cause heat damage to the engine?

Don't think so, after all it's a Factory procedure. If you're worried, have a fan placed in front of the engine. Longer periods of idling can damage things like the plastic oil pump drive gears, but that event was after someone here idled theirs for 45 minutes for some strange reason...

Blocking off the AI (Air injection) system will avoid pipe discolouration, there's a very simple method described here:

Hey Allroads - did you ride the bike much without the snorkel? If not, you should try it. You also need to get the "dB Killers" out of that Arrow Exhaust if they're still fitted - they kill performance.

When I first bought my Thrux, I had the same set-up as you - Arrow 2-2 (baffles out), K&N, dealer map - and got 160 Km (100 miles) before the low fuel light came on. After removing the snorkel (and disabling the AI), this increased to around 180km (over 110 miles) and the bike was noticeably quicker. The next step (which I HIGHLY recommend) is to get rid of the air box baffle and get a proper tune from TTP (I also later installed their "Breathe" intake) - the bike pulls like a friggin' train and I now consistently get 200Km (125 miles) before the fuel light starts to blink at me.

Right now I want to makesure everything is ok with the engine. I called the dealer and they told me that the idling could possibly have damaged something. Kinda of worried. Thanks for your input Pieman, hopefulply you are correct. I honestly couldn't tell that anything was wrong when I rode it yesterday.
